main record

A single 4-shade, low-resolution photo. The core record of 2bit.pics.

Record Key tid Timestamp-based ID

Properties

alt string Optional

Alt text for accessibility.

maxLength: 3000 bytesmaxGraphemes: 300 graphemes
caption string Optional

Free-text caption. Any #hashtags in it are read out by this app's AppView and indexed there; nothing about them is stored on the record.

maxLength: 5000 bytesmaxGraphemes: 500 graphemes
colors array of integer Required

Four 24-bit RGB colors (0 to 0xFFFFFF) corresponding to 2bpp pixel values 0 through 3, where 0 is lightest and 3 is darkest.

maxLength: 4 itemsminLength: 4 items
createdAt string datetime Required

When this photo record was published.

facets array of ref app.bsky.richtext.facet Optional

Annotations of `caption`, in the shape Bluesky uses for rich text - hashtags and mentions today, and whatever this app grows next. Byte offsets index the UTF-8 encoding of `caption`, not its characters. Written by the author's client rather than derived here: what a facet records is what the author meant by a run of their own text, which is theirs to say. This app's AppView refuses any facet whose range falls outside the caption, whose tag doesn't match the text it covers, or whose mention doesn't cover a handle - so an indexed tag or mention always corresponds to something actually written.

maxLength: 64 items
image bytes Required

128x112 2bpp Game Boy Camera tile data: 16x14 tiles in row-major order, 16 bytes per tile (8 rows of low+high bit-plane bytes, MSB-first).

maxLength: 3584minLength: 3584
labels ref com.atproto.label.defs#selfLabels Optional

Self-applied content labels, set by the author. 2bit.pics writes any of porn/sexual/nudity/graphic-media, at most one of which is porn/sexual/nudity; clients blur or warn on labeled photos.
